Airworthiness Directives; McCauley Accessory Division, The Cessna Aircraft Company, Model C35, C72, C74, C75, C80, C86, C87, C92, and C93 Series Propellers

What this AD requires

This amendment revises an existing airworthiness directive (AD), applicable to McCauley Accessory Division, The Cessna Aircraft Company, Model C35, C72, C74, C75, C80, C86, C87, C92, and C93 series propellers, that currently requires initial and repetitive visual and dye penetrant inspections of the propeller hub for cracks. This existing AD also requires a one-time eddy current inspection for cracks in the threaded areas of the propeller hub followed by modification of the hub to contain oil with red dye as a terminating action to the repetitive inspections. This amendment clarifies that a dye penetrant inspection is only necessary if crack indications are found or suspected during the visual inspection. This amendment is prompted by requests from operators for clarification of inspection procedures. The actions specified by this AD are intended to prevent propeller blade separation due to a cracked propeller hub, which could result in separation of the engine from the aircraft and subsequent loss of aircraft control.

Repetitive inspection. Re-inspect every 60 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Text is a compliance-procedures excerpt; the specific propeller models are listed in a preceding applicability provision not captured in this excerpt. Applies to each such propeller regardless of prior modification, alteration, or repair. Requires repetitive visual/dye-penetrant inspection of McCauley propeller hubs for cracks per McCauley Accessory Division, The Cessna Aircraft Company, Service Bulletin (SB) No. 200C, dated January 20, 1994, to prevent propeller blade separation from a cracked hub; cracked hubs must be permanently retired and replaced with a serviceable hub modified per paragraph (c) or an equivalent hub incorporating oil with red dye. Propellers identified with change letter 'R' following the hub model designation and having an oil-fill plug in the side of the hub need only comply with paragraphs (d) and (f).

Whether AD 95-24-05 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 95-24-05 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
